@Kodiak83 some midwives don't bother weighing you again after your booking in appointment. They don't want women to get too hung up on weight gain - also remember, some women will put more on but lose it really quickly afterwards, others will only put a bit on but struggle to lose it.
I had my 31 week appointment on Tuesday, and was quite surprised that she weighed me, but I also had a massive jump on my fundal height measurement (went from measuring spot on at 29 weeks to 4 weeks ahead at 31 weeks). I am literally all bump out the front, though, which is probably why, and the bump is lopsided where baby is laid entirely on my right hand side.
For anyone interested, I had to have a growth scan and baby was estimated at 4lb4, which is 72nd centile at this gestation (31+1).
@mOmShanti round ligament pain is usually worse when you cough, sneeze or move quickly (such as sitting up or turning over in bed). It tends to be up the sides of your bump (rather than more 'internal' (iykwim) and period-pain-like). If that doesn't sound like what you're experiencing, you could have a mild form of pelvic girdle pain. If you know any physios, might be worth having a chat with them as they'd be able to give you a better idea.
